A flue box plays a crucial role in maintaining the efficiency and safety of gas fires. Gas fires, especially those that are decorative and radiant, require a carefully designed pathway for the safe removal of combustion gases. The recessed design of this flue box is particularly well-suited for homes that feature deep chimney breasts. This design not only helps in maintaining the aesthetic appeal of your interior but also ensures that heat loss is kept to a minimum, contributing to improved energy efficiency and performance.

This ensures superior durability, resistance to high temperatures, and minimisation of heat loss. With its solid construction, the box is built to last and withstand the rigours of everyday use.
125mm Springfix Spigot: One of the standout features of this product is the integrated 125mm springfix spigot.

The recessed design not only adds an element of modernity to older homes but also requires precise installation. The 125mm springfix spigot is designed to be intuitive and reliable, yet it is advisable to employ the services of a qualified professional. This ensures that all regulations and safety protocols are adhered to, giving you peace of mind and eliminating the risk of faulty installation.
Additionally, proper inspection post-installation is key. Check that all seals and connections are secure and that there is no unnecessary heat loss. Regular maintenance following installation can further enhance the longevity and efficiency of your gas fire setup.
